Windows 10: Problem Acrobat Reader DC

My build is less than a year old and I am having issues with reading pdf files on Reader DC. This happens when I begin zooming in. Eventually the computer locks up. It happened first with a floor plan, but then I tried it even with just a manual. Again only happens when I enlarge quite a bit. Does not happen on my laptop, with the same files. Here is my build:

CPU AMD - Ryzen 7 2700X 3.7GHz 8-Core Processor
Motherboard Asus - Prime X470-Pro ATX AM4 Motherboard...

Problem Acrobat Reader DC

 

Adobe Acrobat Reader DC

Operating system is Windows 10 Pro, Every time I open Acrobat Reader DC I get the following message:

"Windows - Application Error, The application was unable to start correctly (0xc0000022) Click OK to Close the application"

I am unable to uninstall Acrobat reader DC as it does not show listed in the "Apps & Features"

how can I uninstall this program?

thanks

 

Can't change default app from Acrobat Reader DC to Acrobat


VICTORY AT LAST!!!!
The solution turns out to be installing Reader XI in lieu of Reader DC. Reader XI at can be found at:
Adobe - Adobe Acrobat Reader DC Distribution. Although the page title is Adobe Reader DC Distribution you can select "Reader 11.1.10 English for Windows" in the Step 3 dropdown. The downloaded install file is "AdobeRe11010_en_US.exe".

During the installation a dialogue box allows you to decide if it becomes the default pdf handler.



This option is not available with Reader DC.
During the installation of Reader XI the pdf file association is changed to Edge so you'll need to change it back to Acrobat 9.5. That's it all done. Just remember not to accept and upgrade to Reader DC in the future.

 

Can't change default app from Acrobat Reader DC to Acrobat


I am trying to use the default programs app on the control pabel to set Acrobat 9.5 as the default viewer for pdf files. I also have Acrobat Reader DC installed. Neither program appears on the "set your default programs" screen so I changed it on the file associations screen. But Reader DC is still opening the .pdf files by default. I checked back on the default programs app, and the associations screen still lists Reader DC as the default app. But when I click the change program button it asks me if I want to keep the association with Acrobat 9.5! (see screenshot). This is very odd. How to fix?
